I bought a pair of black AF1's for school from ebay they came and I am 100% sure they are real. I checked extensively for their authentication and they passed every test.
So if you want to get some:
- make sure the guy has a high feedback rating with a constant sale in many other items
- make sure the same item has been sold before and check whether that feedback is good
- contact the seller ask alot of questions, ask themt o post pics to your email
- contact feedback guys and talk to them about the authenticity of their item
know your fakes well, know what they look like
when you get it and its not real complain to paypal
make sure you are actually buying AUTHENTIC REAL GENUINE stuff.
